RA 123 s: Three metaphor-less Algorithms for Economic Load Dispatch Solution

This paper presents Rao-1, Rao-2 and Rao-3 algorithms (RA-123) approach to elucidate Economic Load Dispatch (ELD) problem which has Ramp Rate (RRL), Valve Point Effect (VPE), Prohibited Zones of Operation (POZ), and losses of lines. Besides most of the algorithms which depend on algorithmic-specific parameters, the proposed algorithm is independent of algorithmic-specific parameters. The principle contribution of this paper is to minimize the total generation cost by satisfying several constraints such as generation limits, load demand, valve point loading effect, and transmission losses considering metaphor-less algorithms (RA-123). The objective with VPE is considered to improve the performance of ELD. This paper determines the performance of proposed RA-123 algorithms considering different constraints on each test case system and compares them. To explore, ability of proposed optimization algorithms, these are implemented on test networks having 6, 40 and 110 unit systems and outcomes are compared with results attained by prior optimization algorithms. The evaluation of results shows ability and efficacy of (RA-123) for solving ELD problem.
